Watch on SFlix. Yang Yang, a solitary deaf girl with a passion for free climbing skyscrapers, lives in a silent world without wealth or power, driven only by her untamed and free spirit. Filmmaker Yuen Nanhsi meets her by chance, and their life journeys begin to intertwine. Over five years of filming, their conversations evolve into reflections on each other’s lives as well as their own, and they grow into friends who can explore each other’s worlds and dreams at any moment.
